Question

PowerShell/xml beginner here.... I m trying to append to or remove empty xml nodes using PowerShell as part of a Nuget Package. The xml file has the following format...

<Root>
    <service name="first">
        <item>
        </item>
    </service>
    <service name ="second">
        <item>
        </item>
    </service>
</Root>

首先,我的脚本选择一个服务, 并保存为变量, 如果用户想要选择服务 1...

if ($xml.Root.service.name -eq $serviceName)
{
         $myService = $xml.Root.service
}

Problem is later on, I need to append elements to the node/delete the node... I have something like

    $newNode = $xml.CreateElement( new ...
    .........

    $empty = $myService.SelectSingleNode( ./item )
    $empty.PrependChild($newNode)

但我不能让这个方法工作。

如有任何建议,将不胜感激。

这应该能帮到你

# Get an XML document
$MyXml = [xml] <?xml version="1.0" encoding="utf-8"?><root><service name="foo"><item></item></service></root> ;
# Create a new element from the XmlDocument object
$NewElement = $MyXml.CreateElement( new );
# Select the element that we re going to append to
$ServiceElement = Select-Xml -Xml $MyXml -XPath  /root/service[@name="foo"]/item ;
# Append the  new  element to the  item  element
$ServiceElement.AppendChild($NewElement);
# Echo the OuterXml property of the $MyXml variable to verify changes
Write-Host -Object $MyXml.OuterXml;
# Save the XML document
$MyXml.Save( c:	est.xml );
